Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to control of display attributes when displaying data having attribute-attribute value pairs on a display device.

[0002]

2. Description of the Related Art Up to now, a number of systems have been proposed and commercially available in which an application program running on a computer reflects the data processed by the application program on the display of a display device and presents it to the user.

In these systems, the attributes possessed by the data are converted into display attributes such as coordinate values and colors on the display for display, and most of the conversion is performed for one attribute.
The two display attributes are linearly mapped.

On the other hand, a technique has been proposed in which the coordinate system of the display attributes is transformed to enlarge an arbitrary region and reduce the other regions.

1992 "(Prior Art 1) is transformed by the following equation by the radius component r of the two-dimensional display polar coordinate system. Note that d
Is a distortion factor.

[0006]

[Equation 9]

Further, Japanese Patent Laid-Open No. 7-320079 (Prior Art 2) discloses that when a plurality of modified expressions of Prior Art 1 are used,
That is, in the case where a plurality of enlargement centers are provided, the method of calculating the coordinate values by the respective deformation formulas and taking the average thereof is that the deformation desired by the user cannot be obtained, and the parameters are set by trial and error. Is going to need to. In Prior Art 2, in order to solve this problem, instead of taking an average of a plurality of deformation formulas, a deformation region is determined so as not to interfere with each deformation formula, and the deformation is performed for each region. Is proposed.

Furthermore, "3-Dimensional Pliable Surfac

ation: MSTCarpendale, DJCowperthwaite and F.
D.Francchia, In Proc. UIST'95, 1995 ”(Prior Art 3) uses perspective in a three-dimensional display, and a bivariate Gaussian function generates a display of a plane parallel to the user's line of sight. It is deformed by sticking it on a curved surface.

[0009]

However, in the deformation formula of the prior art 1, the parameter for controlling the deformation is only the distortion factor d, and only a one-dimensional circular deformation is possible. That is, it is not possible to sufficiently cope with the case where only the area represented by a certain rectangle or ellipse is desired to be enlarged.

Further, the prior art 2 states that the parameters must be set by trial and error when the average of a plurality of transformation formulas is taken, but it is hard to think that the user is confused by taking the average, rather. , It is thought that this is a problem that occurs because the transformation formula is inflexible and the user cannot intuitively and freely set the parameters.

Further, in the prior art 3, since the Gaussian function is used, it is possible to perform expressive deformation by using the parameters of the Gaussian function, but the three-dimensional space is used to deform the two-dimensional plane. Therefore, it cannot be applied to three-dimensional data display.

Further, although the above three conventional techniques have at least one parameter for modification, a method for intuitively changing the parameter by the user is not disclosed.

The above three prior arts focus on the mapping to the display coordinate system among the display attributes, but regarding the mapping to other display attributes, the parameters of the function used for the mapping. There is no technology to change. As a similar technique, there are techniques such as a paint tool and a draw tool that generate "gradients of arbitrary rectangular areas", but in many of these, gradation patterns are given in advance,
What the user can control is about the direction of the gradation and the colors of the start / end points.

The present invention enriches the expressive power of the function for mapping the attribute of data to the display attribute, and allows the user to freely and intuitively change the parameter of the function corresponding to the expressive power. It is an object to provide a method, an apparatus and a recording medium.

That is, according to the present invention, when a data group having an attribute is displayed in coordinates and visualized, and a coordinate peculiar to the data based on the attribute is determined by using some function in a place not visible on the display screen, the function is used. By providing a user interface (controller) that controls the parameters of that function, moving the controller changes the data coordinates and changes the display mode, emphasizing the data centered on the controller. The purpose is to display continuously.

Further, as a visual expression, not only the coordinates but also the display attributes such as the display color, the transparency, the filling, and the color / width of the frame line are controlled similarly.

[0017]

[0019]

The above mapping function can achieve the above-mentioned object by using a general function. For example, a hyperbolic function of tangent, arc tangent or their derivative, or Gaussian function is used. By using a function or a function obtained by indefinite integration of the function, a more suitable operation that is compatible with the GUI component can be obtained.

When the mapping function is a mountain-shaped function that maximizes the attribute value of the display attribute with the attribute value of the converted attribute, the maximum value of the display attribute, the attribute value of the converted attribute at that time, Then, one or more of the speeds to the maximum are selected, and the parameter set of the mapping function is selected.
And

[0023] The mapping function is a function that converts a plurality of the converted attribute to one display attribute is the chevron function as the attribute value of the display attribute in the attribute values of the transform attribute is maximal At least one of the maximum value of the display attribute, the attribute value of each converted attribute at that time, the speed to the maximum value of each converted attribute, the correlation between the converted attributes, and the rotation of the parameter space. select, as a parameter set of the mapping function.

[0024] The mapping function is a function for converting a plurality of the converted attribute therewith into the same number of display attributes, and a function that is to be converted attribute is one-to-one correspondence with the display attributes, the gradient of the function When is a monotonically increasing function that maximizes at some attribute value of the converted attribute, the maximum value of the gradient,
Parameter value of the mapping function by selecting any one or more of the attribute value of each converted attribute at that time, the speed to the maximum value in each converted attribute, the correlation between converted attributes, and the rotation of the parameter space. Set as a set.

[0025] The mapping function in a desired attribute value range of the transform attribute, said applying the mapping function or the monotonously increasing mapping function Yamagata, in the range of the translation attributes, performing linear mapping.

At this time, even if the effective attribute value range of the converted attribute of the mapping function is always constant, it may change depending on the speed to the maximum value or the maximum value in the parameter set. Good. When the attribute value range is constant, the mapping function application area can be made constant, while when the attribute value range changes,
It is possible to dynamically change the mapping function application area.

[0027]

[0028] together with the object to be converted attribute is a display attribute,
The translation attributes and the display attribute is the same attribute.

When the mapping function is a function having a plurality of parameter sets, it is preferable that each parameter set can be controlled by one GUI component.

[0050]

BEST MODE FOR CARRYING OUT THE INVENTION <First Embodiment> A first embodiment of the present invention will be described below with reference to the drawings.

According to the present invention, in an application program for displaying data having an attribute-attribute value pair on a display device, a function for associating an arbitrary attribute with a display attribute such as a coordinate value on a display and a color is prepared, and the application program is executed. It provides a way for the user to change the parameters of the function at will.

As a changing means, a GU as shown in FIG.
The I component is prepared, and the parameter of the function is changed according to the operation on the GUI component by the user.

For example, the user can display a message as shown in FIG.
When this GUI part is placed in the area indicated by 005, the display is transformed as shown in FIG. Although it seems that the display is directly deformed in FIG. 6, in reality, the parameters for mapping the attributes 1 and 2 in FIG. 5 to the coordinates of the horizontal axis and the vertical axis of the display respectively are changed. There is. At the same time, the size of the display object 50004 that represents individual data in FIG. 5 is calculated from the attributes 1 and 2. That is, the data having the attribute values of attribute 1 and attribute 2 corresponding to the position where the GUI part is placed is displayed in the largest size, and the data apart from it is displayed in a relatively small size.

First, the function for converting the data attribute to the display attribute and the mapping function will be described.

The mapping function of the present invention is either a mountain-shaped one in which the function has a local maximum or a monotonically increasing one in which the gradient of the function has a local maximum.

The following functions are typical examples of the Yamagata function. The following functions are for univariate.

[0057]

[Equation 1]

A function obtained by indefinite integration of these functions becomes a monotonically increasing function. The first of the three functions listed above
The function of is a Gaussian function, and this indefinite integral is obtained by series expansion. Further, the indefinite integrals of the remaining two functions are the following functions, respectively.

[0059]

[Equation 2]

Here, atan (x) and tanh (x)
Are the inverse of the tangent and the hyperbolic function, respectively.

In the present embodiment, the second function of the three mountain-shaped functions mentioned above is used as the mountain-shaped mapping function, and the monotonically increasing function is the indefinite integral at.
A function based on an (x) is used. The function based on atan (x) is as follows.

[0062]

[Equation 3]

Here, A is an arbitrary coefficient, and α and β are coefficients of the linear component included in the mapping function. That is,
The monotonically increasing mapping function is a function that adds nonlinearity to a straight line determined by the coefficients α and β by atan (x). In this function, if A = 0, it becomes a linear mapping function.

The coefficients α and β of the linear component of the mapping function can be obtained from the range covered by the mapping function. For example, assuming that the mapping function affects the range of (-r, r) centered on 0 in the above equation, and the same value as the linear mapping is taken at the two points of the center and r (or -r), The coefficients α and β can be easily obtained by solving simultaneous equations. Hereinafter, in the present embodiment, the range covered by the mapping function is constant, but the range is not limited to this and may change in conjunction with the parameters of the mapping function described later.

Next, the parameters of the mapping function will be described.

The mapping function of the present invention is characterized by having several kinds of parameters. In the case of a univariate function, there are three types of parameters: the maximum value of the function, the value of the variable at the maximum value (x in the above function) (center), and the speed to the maximum value. In the case of variables, in addition to the three types, there are five types of correlation coefficient of each variable and rotation of the parameter space. With these parameters, rich mapping can be realized.

The bivariate chevron function is represented as follows by using four kinds of parameters excluding rotation among the parameters.

[0068]

[Equation 4]

Μx and μy are the centers of x and y, and σx and
σy is the velocity of x, y, ρ is the correlation coefficient of x, y, and A
Is the maximum value.

Here, the term on which the correlation coefficient is applied in the above function is

[0071]

[Equation 5]

Then, a star with four vertices or an ellipse close to a square can be represented.

For the rotation of the parameters, this function will be described by converting the function into polar coordinates for simplicity.

[0074]

[Equation 6]

When the rotation φ is introduced, the above equation becomes as follows.

[0076]

[Equation 7]

By doing so, the velocity and the correlation coefficient among the parameters of the mountain-shaped function are only φ in the parameter space.

Next, the monotonically increasing function will be described.

Since the monotonically increasing function can be expressed as the indefinite integral of the mountain-shaped function, there is no difference in the meaning of the parameters. However, in the case of a multivariate, a monotonically increasing function has the same number of variables and the same number of display attributes calculated by the mapping function, and each variable and display attribute must be associated in a one-to-one correspondence. In the present embodiment, in the case of multidimensional, the orthogonal coordinate system is once converted into a polar coordinate system, the radial mapping in the polar coordinate system is calculated, and the result is converted into the original rectangular coordinate system.

Further, the velocity parameter after the polar coordinate conversion may be changed according to the angle of the polar coordinate form, instead of the polar coordinate conversion being faithful to the mathematical expression. For example, when the velocity parameter is plotted on the two-dimensional coordinates, it may be changed so that its shape becomes a quadrangle.

The mapping function has been described above as a function in which the monotonically increasing function is atan (x) and the mountain-shaped function is the derivative thereof. You may use the tanh (x) mentioned above, the function which differentiated it, and a Gaussian function. Also, as a mountain-shaped function, a certain mountain-shaped function g (x)
You may use the function of {1-g (x)} when doing.

Next, the GUI component of the present invention will be described by taking a two-dimensional GUI component as an example.

The parameters of the above mapping function are
The maximum value of the function or the maximum value of the gradient, the attribute value of the converted attribute when it is maximum, the standard deviation of the converted attribute, the correlation coefficient between the converted attributes, and the rotation of the parameter space are 1
Treated as one parameter set. In the present invention,
A GUI component that allows a user to control a parameter set. FIG. 4 shows an example thereof.

The GUI part 40000 of FIG. 4 has a double circular ring shape, and is roughly divided into an inner circle 40010 and an outer circle 4002.
It consists of zero. The outer circle 40020 is divided into eight arcs 40021 to 40028 depending on the angle from the center of the GUI component.

The degree of freedom of operation of this GUI part is the position of the inner circle 40010 (equivalent to the position of the GUI part) in the display, the color of the inner circle 40010, and the distance from the center for each outer circle arc. The outer shape is changed by the operation to each part by, and the value of the corresponding parameter is changed. FIG. 14 shows a list of degrees of freedom of operation of GUI parts, parameters, and operation methods.

It is assumed that all the operations are performed by the mouse having two or more buttons, and the operation is started by pressing the button on each part of the GUI component, and the mouse is moved while the button is in the pressed state, that is, The principle is to drag. For example, to move the center of the parameters, the user moves the mouse cursor over the inner circle 40010 and presses button A,
While pressing button A, main body 40010 is moved to a desired position on the display.

Further, the outer circular arc is paired with the arcs on the diagonals. For example, 40021 and 40022 are paired as an arc representing the x standard deviation, and when the user performs an operation to expand the arc 40021 to the right, the arc 40022 expands to the left by the same amount in synchronization with it, and the x standard deviation also increases. Correspondingly changes.

Further, the arc 40 to which the correlation coefficient is assigned
In 025 to 40028, the pair of arcs 40025-40026 and the pair of arcs 40027-40028 are interlocked and deformed. For example, if the correlation coefficient term in the mapping function is

[0089]

[Equation 8]

If it is calculated that
Alternatively, the movement to the outside of 40026 changes the correlation coefficient in the positive direction, and the arcs 40027 and 40028 are moved to the inside by that amount.

Next, the operation of the present invention will be described with reference to the flowchart of FIG.

In FIG. 3, the part on the left side of the broken line is a typical flow of an application program using the data display control method of the present invention, and the part on the right side of the broken line is the GUI component and the processing performed by the mapping function. It is a flow.

First, the processing performed by the GUI component and the mapping function will be described.

The processing using the GUI component and the mapping function is performed in steps 30101, 30102 to 30104, 30105, and 3
It has four procedures of 0106, and these processes are appropriately called from the application program.

In step 30101, the mapping function / GUI component registration unit 20101 shown in FIG. 2 receives a request from the application program to newly register the mapping function and the GUI component, and newly registers the mapping function and the GUI component.

Steps 30102 to 30104
Is a procedure for processing the user's input operation to the GUI component. First, in step 30102, the GUI component input management unit in FIG.
Determine if it was done for a part. If the determination cannot be made here, the process is returned to the application program, and if the determination can be made, the ID of the parameter set corresponding to the ID of the GUI component is stored for the subsequent steps. Then, in the next step 20103, the parameter of the parameter set indicated by the parameter set ID is changed in the mapping function parameter changing unit 20103 of FIG. 2, and in the step 30104, the GUI component I is changed in the GUI component outline changing unit 20104 of FIG.
The outer shape information of the GUI component indicated by D is changed. After completing these procedures, the process is returned to the application program.

Step 30105 is a procedure for converting the attribute value of the converted attribute into the attribute value of the display attribute when the attribute value of the converted attribute is sent from the application program in the data attribute → display attribute changing unit 20103 of FIG. .

Step 30106 is the GUI of FIG.
In the component display generation unit 20106, in response to a display generation request from the application program, a display is generated using the latest outline information for all registered GUI components.

Next, the flow on the application program side will be described.

The application program is described as an event driven type. In step 30001, it is determined whether or not the user has performed an input operation on the input device 21000.
If there is no input operation, the process proceeds to step 30003, and if there is, the process proceeds to step 30002.

In step 30002, the type of input operation is determined. Here, the input to the GUI component of the present invention,
If it is the registration input of the mapping function / GUI component, the process proceeds to the above-mentioned step 30102 and step 30101. If the input operation is another input operation, the process proceeds to step 30003.

If there is no input operation in step 30001, or if the input operation is G in the present invention in step 30002.
If it is not related to UI parts, step 3
At 0003, processing unique to the application is performed.

When step 30003 ends, the necessity of generating a display is checked in step 30004. If display generation is not necessary, the process returns to step 30001. If display generation is necessary, the process proceeds to step 30005.

In step 30005, it is determined whether or not the attribute value of the arbitrary attribute is converted into the attribute value of the display attribute. If it is determined that the conversion is necessary, the above-mentioned step 30105 is called, and Convert the attribute value of the attribute to the attribute value of the display attribute. Step 30105 is called by the number of attribute values that need to be converted, and if there are no more attribute values that need to be converted, the process proceeds to step 30006.

In step 30006, a display is generated using the attribute value of the converted display attribute and the like. And step 3
In 0007, it is determined whether or not the GUI component of the present invention is used. If not, step 3000
Go back to step 1 and step 301 above if used.
The procedure proceeds to 06, and then returns to step 30001.

<Second Embodiment> In this embodiment, a change in display when the data display control method of the present invention is used will be described.

FIG. 5 shows an example of a display screen before arranging the GUI parts of FIG. 4 on the data display. In this example, among the attributes of the data, the horizontal axis 50001 is assigned to the attribute 1 and the vertical axis 50002 is assigned to the attribute 2, and display objects 50004 representing individual data are arranged. That is,
It means that the attribute 1 and the attribute 2 are mapped to the display attributes of the horizontal axis and the vertical axis of the display respectively. In addition, 500
03 is a grid.

Here, attribute 1 and attribute 2 are the converted attributes.
And a mapping function 1 of a monotonically increasing type that converts each to the horizontal axis and the vertical axis of the display attribute, and similarly takes attribute 1 and attribute 2 as the converted attributes to obtain the size of the display object among the display attributes. A mountain-shaped mapping function 2 is prepared, and the parameter set of this mapping function is shown in G of FIG.
Consider controlling with UI components. In this case, the converted attributes are the same for both, and the parameters are also the same, so the parameters of the two mapping functions are set to one GUI.
It shall be able to be controlled by parts. Also, GUI
It is assumed that the parameters of the mapping function are assigned to each degree of freedom of operation of the component as shown in FIG.

FIG. 6 shows a display example when the GUI part is placed at the position of 50005 in FIG.

As can be seen from the transformation of the grid, the mapping function 1 changes the mapping of attribute 1 and attribute 2 to the display coordinate system. In addition, the GUI function is mainly used under the influence of the mapping function 2 so as to synchronize with the deformation.
The size of the display object changes according to the distance from the GUI component in the display.

7 to 13 are display examples when the parameters of the mapping function are changed by operating the GUI parts. The relationship between each figure and the contents of parameter changes from FIG. 6 is shown below.

[0127]

[Table 1]

Here, the correlation coefficient (type1) of FIG.
And the difference in the correlation coefficient (type 2) between FIG. 11 and FIG.
This is due to the difference in calculation of the correlation coefficient term in the mapping function described in the first embodiment. In type1

[0129]

[Equation 4]

As for type2, the correlation coefficient term is

[0131]

[Equation 5]

Is obtained as follows.

FIG. 20 shows a display example in which two GUI parts are arranged in the display of the mapping function shown in FIG. Both of these GUI components control mapping functions similar to those in the examples of FIGS. 6 to 13, and each GUI component is used to change parameters of different parameter sets. In the present embodiment, first, the attribute value of the display attribute is calculated individually for each of the two parameter sets, the average is taken in the case of a monotonically increasing function, and the values of the two functions are taken in the case of the mountain-shaped function. By adding them up, the attribute value of the desired display attribute is calculated.

When a plurality of displayed GUI parts are selected by the user's predetermined input operation,
The parameter change operation for one of the other G
The parameters of the mapping function assigned to the UI component may be changed. For example, a GUI
When an operation is performed to increase the speed parameter of a part, the speed of the mapping function assigned to that GUI part is high, and the speed of the mapping function assigned to other GUI parts is reduced. Good.

<Third Embodiment> This embodiment is the G of the present invention.
It is for controlling a three-dimensional mapping function of the UI parts. The three-dimensional GUI component is a two-dimensional double toroidal representation using a sphere.

In FIG. 18, 180010 is the inner sphere of the GUI part, and 180021 to 180026 are the curved surfaces of the outer sphere. Similar to the two-dimensional GUI part of the first embodiment, the position of the inner sphere 180010 represents the center of the parameter set of the mapping function, 180021 and 180022 are x standard deviations, 180023 and 180024 are y standard deviations, 180025, 180026 represents the z standard deviation.

In the three-dimensional GUI component of the present invention, the inner sphere 180010 rotates in the direction opposite to the rotation angle of the display when the three-dimensional display is rotated. And the inner sphere 18
When an arbitrary surface (region) of 0010 is selected, the movement operation to the inner sphere is restricted so that only the normal direction of the surface is selected until the selection is canceled.

FIG. 19 is a rotation of the three-dimensional display of FIG. 18 and 19, surface A is the same surface of the main body. That is, curved surfaces 180021 to 18002
6 rotates as the display rotates, but the body 180010 appears to be stationary to the user viewing it due to its own rotation.

In FIG. 19, when the plane A is selected and a movement operation is performed, for example, in the case of a plus movement operation, a direction out of the main body in the normal direction of the plane A (front side to the user). ), If the operation is a negative movement, the GUI component moves in the direction of the inside of the main body (back side with respect to the user). This is the same for the other side of the body 180010.

By repeating the above operation and the rotation of the three-dimensional space, it becomes possible to freely move the GUI component in the three-dimensional space.

Curved surface 1 showing the standard deviation of each axis
80021 to 180026 move according to the rotation of the three-dimensional display. That is, the curved surfaces 180021, 18 are always
The straight line connecting the centers of 0022 is the x-axis and the curved surface 18002.
The straight line connecting the centers of 3 and 180024 is in parallel with the y axis, and the straight line connecting the centers of the curved surfaces 180025 and 180026 is in parallel with the z axis. Then, for example, when the user makes a positive movement operation on the curved surface 180021, the curved surface 180021 is moved in a direction away from the main body in parallel with the x axis, and when a negative movement operation is made,
Move parallel to the x-axis in the direction toward the body.

Further, the above-described plus movement operation and minus movement operation may be defined as follows.

First, with respect to the normal line of the target surface (in the case of a curved surface, the surface in contact with the center of the curved surface), the outward direction of the GUI component is the positive direction, and the inward direction is the negative direction. Then, the target surface and its normal are projected onto a plane parallel to the user's line of sight, and the direction in which the mouse cursor moves by the user is relative to the direction of the normal. Whether or not the moving direction is positive or negative is determined by the presence or absence.

With the above arrangement, the GUI component of the present invention can be freely moved within the three-dimensional display.

<Fourth Embodiment> In the present embodiment, in the case where a plurality of mapping functions exist, the operation of two or more mapping functions and the restrictions on the parameter control of the mapping functions will be described in detail.

The calculation of the mapping function is necessary for uniquely determining the attribute value of the display attribute when a plurality of mapping functions control the same display attribute in the same data display as shown in FIG. There are several types of operations, and as a typical example, in the case of a mountain-shaped mapping function, the average, maximum value, minimum value, and product of the return values of the mapping function are listed. In the case of a function, the return value of the mapping function having the largest average, composition, and gradient can be given. Which of these operations is adopted is arbitrary, but it is effective to let the user select it from a menu or the like.

Further, the constraint regarding the parameter control of the mapping function means that when there are a plurality of mapping functions having a constraint relationship, when the parameter of any mapping function is changed, the parameters of other mapping functions are also changed. It is subject to change. That is, when the user operates a GUI component to which a certain mapping function is assigned or the application program changes the parameters of an arbitrary mapping function, the parameters of the mapping function having a constraint relationship with those mapping functions are also changed. That is why.

For example, when two mapping functions exist on the same display as shown in FIG. 20, when the position of one mapping function is moved using the GUI component, the other also moves at the same time, and the speed on the horizontal axis of one moves. There is a constraint such that the larger the value of, the smaller the speed of the other.

In this embodiment, two types of constraints are prepared. One is a constraint between two mapping functions, and the other is a constraint between arbitrary mapping functions in the group with a plurality of mapping functions as a group.

First, regarding the former, the parameter sets of two mapping functions having a constraint relationship are respectively defined as a and b, and the change amount of the parameter contained in b when the user operates the parameter contained in a is used as a function. The following is the expression.

[0151]

[Equation 10]

I and j are identifiers representing the parameters contained in a and b, respectively. When i = j, the same parameters are controlled. Further, there may be a plurality of parameters corresponding to the arguments of the function. The above equation represents the change of the parameter contained in b when the parameter contained in a is operated, and generally does not represent the reverse. However, if the opposite is always true, the inverse relationship can be expressed by the inverse function of the above equation.

In the latter, when a parameter included in the parameter set of a certain mapping function in the group is operated by the user, an arbitrary parameter included in the parameter sets of all other mapping functions is changed. It is a constraint. When the parameter set of the mapping function operated by the user is a and the parameter set changed at the same time is b, the change amount of the parameter included in the parameter set b is the same as the former. However, the difference in the meaning of the function between the two is that the former shows the parameter sets a and b as a specific parameter set, whereas in the latter case the parameter sets a and b are different from the arbitrary parameter sets belonging to the group. Is to be.

FIG. 21 is a block diagram for realizing, as a system, constraints relating to calculation of a plurality of mapping functions and parameter control. The difference from the block diagram in Figure 2 is
This is to add the mapping function constraint group information 2015, the mapping function operation group information 2016, and the reference relationship of data necessary for these.

Mapping function calculation group information 2011
6 and the mapping function constraint group information 20125 are shown in FIGS. 22 and 23, respectively. Both are arithmetic,
Alternatively, a plurality of mapping functions to be restricted are managed as a group.

Mapping function calculation group information 2011
6 is described as a table including a group ID, a list of mapping function parameter set IDs, and operation types. The group OG001 in FIG. 22 is composed of three parameter sets PS001, PS002, and PS003, and means to take the average of the calculation results of the mapping functions corresponding to the individual parameter sets.

Mapping function constraint group information 2
In 0115, the management unit of constraints is a group in a broad sense for both of the above-mentioned two types of constraints. That is, in the case of a type having a constraint between any two mapping functions, those two mapping functions are treated as one group.

FIG. 23 shows an example of the description, group I
It is described as a table including D, a constraint type, a list of parameter set IDs, a function for calculating a parameter change amount due to a constraint, and a parameter type as an argument of the function and a parameter type of a return value of the function.

The constraint type represents the above-mentioned two types of constraints. In FIG. 23, the constraint between the two mapping functions is OneToOne, and the constraint in the narrow sense group is Gr.
It is up. Also, in the case of the OneToOne type, the two mapping functions must be explicit in "constraining side a" and "constrained side b" in the constraint function. In this embodiment, in the list of parameter set IDs, the "constraint side a" is described as the first item in the list, and the "constraint side b" is described as the second item in the list. Figure 2
3 pa and pb represent the parameters of the “constraining side a” and the “constraining side b”, respectively,
As described above, when the constraint type is Group, a or b
Is an arbitrary parameter set included in the group.

Next, FIG. 21 will be described in detail.

In FIG. 21, the mapping function / GUI
The component registration unit 20101 uses the application program 2
In response to a request from 0000, a mapping function and a GUI component for controlling the mapping function are provided in a GUI component-parameter set correspondence table 10112, GUI component information 20113,
Then, it is registered in the mapping parameter information 20114 in a format described later.

From the application program,
When there is a request to register a plurality of mapping functions as an operation group, the plurality of mapping functions designated by the application program are added to the mapping function operation group information 2016 as an operation group.

From the application program,
When there is a request to register a plurality of mapping functions as a constraint group, the plurality of mapping functions specified by the application program are added to the mapping function constraint group information 20155 as a constraint group.

When the above three types of registration have been performed, the GU is respectively applied to the application program 20000.
A pair of I-part ID and parameter set ID, operation group ID, and constraint group ID are returned.

The GUI part input management unit 20102 is particularly the input control unit 2 in the application program 20000.
Whether or not the input operation information sent from 0010 is an input for a GUI part, a GUI part-parameter set correspondence table 20112 and an input operation-GUI part operation degree of freedom correspondence table 2
The determination is made by referring to 0111. Here, if it is an input operation for a GUI component, the GUI component outer shape changing unit 201 displays the ID number and the operation variable of the GUI component that is the input operation target.
04, and the parameter set ID of the mapping function corresponding to the GUI component that is the operation target and the operation variable are sent to the mapping function parameter changing unit 20103.

In the GUI part external shape changing section 20104, G
The outline information of the GUI component described in the GUI component information 20133 is rewritten based on the GUI component ID and the operation variable sent from the UI component input management unit 20102, and the mapping function parameter changing unit 20103 uses the GUI component input managing unit 20102. Parameter set ID sent from
And mapping function parameter information 201 based on the operation variable
Parameter information described in 14 is rewritten.

Further, the mapping function parameter changing unit 20103 uses the mapping function constraint group information 2011.
5, a constraint group including the corresponding parameter set ID is searched for. Here, if a corresponding group exists, the constraint of the group is executed to change the parameter, and the mapping function parameter information 20114
Rewrite. Then, the parameter set ID whose parameters have been changed due to the constraint, the changed parameter, and the changed value are sent to the GUI component outline changing unit 20104, and the GUI component outline changing unit 20104 refers to the GUI component-parameter set correspondence table 20112, Change the outline of the corresponding GUI component.

If necessary, the GUI component outline changing unit 20104 queries the GUI component → display attribute changing unit 20105 to change the position of the GUI component. This necessity arises when the coordinate value is determined by the calculation of the mapping function in the case where the display attribute is the coordinate in the data display and a plurality of GUI parts are displayed in a manner overlapping with the data display. The position of the GUI component represents the central parameter of the corresponding mapping function, and in the case of a single mapping function, it may have a value proportional to the central parameter of the mapping function. However, when the calculation of the mapping function is present, if the position is used as it is, the actual display and the position of the GUI component are deviated, and the user may feel uncomfortable. In order to eliminate the discomfort, the GUI component → display attribute changing unit 20105 is queried to calculate the center position of the GUI component, and the GUI component information 20113 is updated.

Here, in order to judge the necessity of such position correction of the GUI parts, in the GUI parts-parameter set correspondence table 20112, the individual GUI parts-
It suffices to describe the type of display coordinates to be controlled for the pair of parameter sets. This information is sent from the application program 20000 when the application program 20000 makes a registration request to the mapping function / GUI component registration unit 20101.

Data attribute → display attribute conversion section 20105
Is the mapping function calculation group information 20116 and the mapping function parameter information 20 for the calculation group ID or parameter set ID and the attribute value of the converted attribute sent from the application program 20000.
114, the attribute value of the converted attribute is converted to the attribute value of the display attribute, and the converted attribute value is returned to the application program.

Also, the GUI component display generation unit 20106
GUI component information 20 in response to a request from the display control unit 20020 of the application program 20000.
The current GUI part outline is generated by referring to the outline information of the GUI part described in 113.

Next, the operation of the present invention will be described with reference to the flowchart of FIG.

In FIG. 3, the part on the left side of the broken line is a typical flow of an application program using the data display control method of the present invention, and the part on the right side of the broken line is the GUI component and the processing performed by the mapping function. It is a flow.

First, the processing performed by the GUI component and the mapping function will be described.

The processing using the GUI component and the mapping function is performed in steps 30101, 30102 to 30104, 30105, and 3
It has four procedures of 0106, and these processes are appropriately called from the application program.

In step 30101, the mapping function / GUI component registration unit 20101 of FIG. 2 performs an appropriate registration operation in response to the registration request from the application program. The registration request from the application program is one of registration of a mapping function and a GUI component for controlling the mapping function, registration of an operation of a plurality of mapping functions, and registration of a constraint of a plurality of mapping functions. A pair of component ID and parameter set ID, operation group ID, and constraint group ID are returned.

Steps 30102 to 30104
Is a procedure for processing the user's input operation to the GUI component. First, in step 30102, the GUI component input management unit in FIG.
Determine if it was done for a part. If the determination cannot be made here, the process is returned to the application program, and if the determination can be made, the ID of the parameter set corresponding to the ID of the GUI component is stored for the subsequent steps.

Then, in the next step 20103, the value of the parameter of the parameter set indicated by the parameter set ID stored in the mapping function parameter changing unit 20103 of FIG. 2 is changed, and the parameter set (mapping function) is changed. Change the value of the parameter of the parameter set that has a constraint relationship.

Next, in step 30104, the GU of FIG.
GUI stored in the I-part external shape changing unit 20104
The GUI corresponding to the parameter set whose parameter value has been changed by the constraint in step 30104 while changing the outline information of the GUI part indicated by the part ID
Change the outline information of parts. At this time, if it is necessary to correct the position of the GUI component, the position of the GUI component is updated using step 30105 described later.

After completing these procedures, the process is returned to the application program.

In step 30105, in the data attribute → display attribute changing unit 20103 of FIG. 2, when the attribute value of the converted attribute and the parameter set ID or the calculation group ID used for conversion are sent from the application program, This is a procedure for converting it into the attribute value of the display attribute.

Step 30106 is the GUI of FIG.
In the component display generation unit 20106, in response to a display generation request from the application program, a display is generated using the latest outline information for all registered GUI components.

Next, the flow on the application program side will be described.

The application program is described as an event driven type. In step 30001, it is determined whether or not the user has performed an input operation on the input device 21000.
If there is no input operation, the process proceeds to step 30003, and if there is, the process proceeds to step 30002.

At step 30002, the type of input operation is determined. Here, the input to the GUI component of the present invention,
If the registration input of the mapping function / GUI component, the calculation group registration of the mapping function, or the constraint group registration of the mapping function is performed, the above-described step 3010 is performed.
2. Go to step 30101. If the input operation is another input operation, the process proceeds to step 30003.

If there is no input operation in step 30001, or if the input operation is G in the present invention in step 30002.
If it is not related to UI parts, step 3
At 0003, processing unique to the application is performed.

Upon completion of step 30003, the necessity of generating a display is checked in step 30004. If display generation is not necessary, the process returns to step 30001. If display generation is necessary, the process proceeds to step 30005.

At step 30005, it is determined whether or not the attribute value of an arbitrary attribute is converted into the attribute value of the display attribute, and if conversion is necessary, the above-mentioned parameter set ID or calculation group ID used for conversion is added. Step 301
05 is called and the attribute value of the attribute is converted into the attribute value of the display attribute. Step 30105 is called by the number of attribute values that need to be converted, and if there are no more attribute values that need to be converted, the process proceeds to step 30006.

At step 30006, a display is generated using the attribute value of the converted display attribute. And step 3
In 0007, it is determined whether or not the GUI component of the present invention is used. If not, step 3000
Go back to step 1 and step 301 above if used.
The procedure proceeds to 06, and then returns to step 30001.

<Fifth Embodiment> In this embodiment, an application system using the data display control method of the present invention will be described with reference to a display example. Typically,
Although any data search / reference system using computer graphics may be used, this embodiment will be described by taking a system for referring to data of residents living in a certain area as an example.

The data has five attributes, which are name, age, height, weight and portrait. The attribute values of these attributes are stored for each individual. The name is 1 here to protect the privacy of the individual.
Encrypt in hexadecimal.

A display example of this system is shown in FIG. The entire display 240000 is roughly classified into a main display unit 240100 for plotting data by taking the height and weight on the horizontal axis and the vertical axis, and an age specifying unit 24020 for specifying the age.
0, the detailed information display section 240 that lists the information of any individual
It consists of 300.

On the main display section 240100, one individual is assigned to one graphic object 240500 and all the inhabitants are plotted. Main display 240100
By referring to, the correlation between the height and weight of the residents in the target area is well understood. Further, the size of the graphics object 240500 is arbitrarily changed by the enlargement function described later, and when it becomes a certain size or larger, the portrait of the individual assigned to the graphic object is displayed.

The age designation unit 240200 designates the age in a slider format using the GUI component 240201 of the data display control method of the present invention. Age is GUI part 24
The mountain-shaped mapping function assigned to 0201 maps to the thickness of the frame line of the graphic object 240500 displayed on the main display unit 240100. That is, the GUI component 240 on the slider
The position of 201 represents the central parameter of the mapping function, that is, the age of the center, and the upper and lower ends of the outer ring and the GU.
The distance from the center of the I-part represents the speed parameter, that is, the width of the specified age. As a result, the frame line of the graphic object 240500 that represents an individual whose age is close to the central age becomes thicker, and the frame line becomes thinner as the distance increases, and the width of the frame line becomes 0 for those outside the specified age range, and the frame line becomes 0. Disappears. Further, a correspondence graph 240202 is drawn in order to facilitate understanding of the relationship between the age and the thickness of the frame line. When the GUI component 240201 is moved, the graph is also moved at the same time, and when the outer ring of the GUI component 240201 is pulled in the vertical direction, the bottom of the graph is widened.

The thickness of the frame line changed by the operation of the GUI component 240201 is displayed in real time on the main display section 24.
The display is updated by being reflected in the graphic object 240500 of 0100. In FIG. 24, the GUI component 240201 is placed at the position of 45 years old, but when it is moved to the position of 58 years old, the display as shown in FIG. 25 is made.
As described above, the relationship between height, weight, and age can be easily referred to in the main display 240100 simply by controlling the mapping between the age and the thickness of the frame line of the graphic object in the age designation unit 240200.

Here, the user's interest is "height is 150 cm.
Suppose that he wanted to know what kind of person there was in the vicinity of the data set around a body weight of around 80 kg. In order to meet the needs of such a user, the system of the present embodiment, as in the second embodiment,
It has the function of transforming the display coordinate system and enlarging the display of graphic objects. To explain this function in detail, the display position of the graphics object is mapped using the monotonically increasing mapping function, and the size of the object is mapped using the mountain mapping function, and the parameters of these functions are set by the GUI component 24010.
It is possible to control with 1 at the same time. The difference from the second embodiment is that the second embodiment has a constant range to which the monotonically increasing mapping function is applied.
In this embodiment, the range changes in proportion to the speed parameter.

FIG. 26 shows that the area of interest of the user is G
It is a display example when the UI component 240101 is placed. Since the data are arranged side by side in the region of interest, the user refers to portraits of people included in the region of interest with the GUI component 240101 being horizontally long. GUI parts 24010
By making 1 horizontally long, the display outside the region of interest can be left as a linear mapping, and the entire image of the data is preserved.

Further, in FIG. 26, the detailed information display section 24
The detailed information of the person in 0300 is displayed. The detailed information display unit 240300 is the main display unit 240100.
The detailed information of the individual whose weight calculated from the enlargement ratio of the graphic object and the thickness of the frame line in (1) is a certain value or more and whose value is the maximum is displayed. In other words, when the height and weight are specified on the main display unit 240100 and the age is specified on the age specifying unit 240200, the data having the highest hit rate among the data satisfying these conditions is displayed on the detailed information display unit 240300. That is why.

Further, the GUI component used in this embodiment has a GUI instruction according to a user's instruction in order to prevent the graphic object from being difficult to see by itself.
It has the function of making parts other than the frame border transparent. FIG. 27
26 is a display example when the GUI component 240101 is made transparent in FIG. The user's instruction can be realized by, for example, an operation of double-clicking while the mouse cursor is over the GUI component. Further, it is preferable that the display returns to the original when double-clicking is performed in the state where the display is transparent.

In FIG. 28, the GUI component 240101 is operated in the main display unit 240100 from the state of FIG. 26 to change the parameters of the mapping function, and further the GUI component 240201 is changed to 33 in the age designation unit 240200.
This is the display when the user moves around. The GUI component 240101 is transparent.

Next, one GUI component is added to the main display 240100. The display at this time is shown in FIG. In FIG. 29, all graphic objects are 2
The position and size of the GUI component are determined by the calculation of the mapping function assigned to each GUI component. By doing so, the details of the two regions can be referred to at the same time. Here, the mapping function assigned to the two GUI components is constrained to move the central parameter at the same time. FIG. 30 shows a display when the center of one GUI component is moved in this state. Figure 3
As can be seen from 0, the two GUI parts are moving at the same time while keeping a certain distance due to the constraint.

Sixth Embodiment In this embodiment, it is shown that a multidimensional mapping function can be expressed as a function of a function representing an arbitrary shape.

In the first to fifth embodiments of the present invention, as a one-dimensional mapping function, the mountain-shaped function is

[0204]

[Equation 1]

Using the second equation of the equation group shown by, the monotonically increasing function is

[0206]

[Equation 3]

Was used.

In the case of multi-dimensions, the basis of the function is the above two expressions, and the variable x in the above expression is replaced with a function representing an arbitrary shape. That is, in the case of a two-dimensional mapping function, if a function expressing an arbitrary shape is R (x, y), a mountain-shaped function is g (R (x, y)) and a monotonically increasing function is f (R).
(X, y)). Here, suppose R (x, y) is expressed as the following equation.

[0209]

[Equation 11]

This function represents an arbitrary ellipse,

[0211]

[Equation 4]

It can be seen that the mountain-shaped mapping function represented by and the monotonically increasing mapping function represented by the indefinite integral of Equation 4 are functions of an ellipse.
Due to the influence of this function, the coordinate transformation shown in the first to fifth embodiments is elliptical. However, the transformation of coordinates is
The shape of R (x, y) is visually reproduced when the application range of the mapping function changes in proportion to the velocity parameters σx and σy. Therefore, in the second embodiment, the applicable range is constant irrespective of the speed parameter, and therefore the display examples FIGS. 6 to 13 are not visually elliptical.

In the double-ring GUI component of the present invention, if the outer circle is shaped based on R (x, y), the user can intuitively understand the current state of mapping.
